Filling
Fill the space between the floor and the damper as indicated in the
drawing.
Sealing with concrete is not allowed.
1. Positioning brackets
2. Screw Ø 3,5 X 35 mm or equivalent
3. Fire damper
4. Ventilation duct
5. Rock wool 35 kg/m³, or mortar or plaster putty
6. Fire stopping sealant (reference Soudal Firecryl or equivalent with
resistance and reaction to fire equal or higher) to cover the sealing
7. Fire stopping sealant (reference Soudal Firecryl or equivalent with
resistance and reaction to fire equal or higher) between refractory ring
and construction support
D from nominal diameter min + 30 to nominal diameter max + 55
Installation remote from the rigid wall
Refer to the section Construction supports characteristics for further
information.
Comply with the minimum distances indicated on section Minimum
distances .
Before and after installation please perform a functional test. Refer to
section Mechanism type for further information .
Wall opening
A opening must be provided in the wall as indicated in the table and
in the drawing
Damper positioning
Connect fire damper to the galvanized steel duct as indicated in the
drawing.
Install the damper with the mechanism facing away from the wall as
indicated in the drawing.
The fire damper has to be fixed and suspended from the ceiling as
indicated in the drawing.
For distance between fire damper and wall less than or equal to 1m,
only one support is enough as indicated in the drawing.
The support at 20 mm from the fire damper is always mandatory.
Close the blade before installing the fire damper.
Filling
Fill the space between the wall and the damper as indicated in the
table and in the drawing.
Sealing with concrete is not allowed.
Cover the duct over its entire length and fire damper as indicated in
the drawing wrapping it with insulation rock wool Pro Wired Mat 80
AL 1 Paroc with density of 80 kg/m³ and thickness 70 mm or equi-
valent.
A metallic mesh is installed around the rock wool. The junctions
between the insulation and the damper are made by an acrylic fire
stopping sealant (es. Soudal Firecryl or equivalent with resistance
and reaction to fire equal or higher), as indicated in the drawing.
